Phosphonoadipic acid additives to aqueous systems

A compound or mixture of compounds of the general formula: STR1 in which m and n may be 0 or 1 but both cannot be 1, R1, R2, R3, R4, R5 and R6 are independently H or CH3, X1, X2, Z1 and Z2 are independently hydrogen or straight or branched chain C1 -C4 alkyl; and the water-soluble inorganic or organic salts thereof, with the proviso that at least one of R1, R2, R3, R4, R5 must be CH3, and when m and n are both 0, R2 and R3 are each methyl and R4 and R5 have their previous significance, when added to an aqueous system imparts one or more of the following beneficial effects to be treated system: (a) the corrosion of ferrous metals in contact with the system is inhibited; (b) the precipitation of scale-forming salts of calcium, magnesium, barium and strontium from the treated aqueous system is inhibited; and (c) inorganic materials present in the treated aqueous system are dispersed.
